I've been using TiddlyWiki for some
years as a personal wiki space and although the first version was a bit
clumsy about saving and searching ; today, it is the most re-usable, portable,
easily shared self-contained wiki that you can find to manage your local tasks
and information.

Mainly, I use TiddlyWiki to maintain notes, store and manage links. While
there are online sites like Delicious and Stumbleupon which facilitate users
sharing weblinks, they dont have the highly customizable features that
Tiddlywiki has ; namely, the freedom to customize, edit pages and add oodles of
content (ex. store phone nos, or other personal data which you dont want to
store on a public space). Sometimes, I want to add IRC conversation snippets or
installation notes as a future reference for something I had tried previously
and found useful and it makes it very easy to add new tiddlers instantly. This
level of fine-grained user-level customization is not available in any online
site.

I wanted to share this so that folks who like wikis for the ease of editing
can use Tiddlywiki instead of struggling to maintain local wiki installations
on their servers. Dont forget that Tiddlywiki is the only wiki that does not
need a server-side implementation and runs entirely on your browser.

TiddlyWiki is built on a combination of HTML, CSS and JavaScript and you can start by
downloading an empty.html page to start using it. Here is the sourcecode if you want to contribute new
features, and they also have a community
space, some tutorials, a bug
tracker, and many freely available themes to customize your local wikipage.
In short, the uses are as (un)limited as your imagination is. Enjoy!
